The nanoscale integration of heterostructures in chemo- and bio-catalysis
Galen D. Stucky Department of Chemistry & Biochemistry and Materials Department, University of California, Santa Barbara, California 93106 USA Abstract
During the past twenty years improvements in synthesis and characterization capabilities have made possible the designed molecular assembly of complex materials with spatially distinct, multifunctional features that are hierarchically structured. These materials are systems in their own right, with property variables that can built in or used in a dynamic mode. This offers a challenging, but very real opportunity to control chemo- and bio-processs systems. An example is given of the use of high-surface-area inorganic interfaces to control the catalytically driven bioprocesses of a biosystem of some complexity, followed by a selected overview of some recent strategies for the synthesis of multicompositional functional units and their use in controlling processes in chemo catalysis. Keywords biosystems catalytic systems interfaces bioprocess control heterostructured materials 1 Introduction
Living biosystems provide a sophisticated catalysis model that is currently well beyond the best bench-top and commercial efforts (Barnes 1986; Rich 2003; Litvin 2009; O’Driscoll 2007). In biogenesis, the components of the organized, integrated, multicomponent system are created and function via non-linear, frequently autocatalytic processing. The bioprocess is typically directed by entropy change and interface inter-actions in confined spaces with high fidelity selectivity at the atomic scale. The biosystem space/time assembly definition of structure and function makes possible the closely coupled organization and processing of integrated organic and inorganic domains. In their Introductory Perspective to a Special Feature of the Proceedings of the National Academy of Sciences on “Complex systems: From Chemistry to Systems Biology”, John Ross and Adam Arkin (Ross 2009) summarize it succinctly and well. “There is great interest in complex systems in chemistry, biology, engineering, physics, and gene networks, among others. The complexity comes from the fact that in many systems there are a large number of variables, many connections among the variables including feedback loops, and many, usually nonlinear, equations of motion, or kinetic and transport equations. “Many” is a relative term; a properly interacting system of just three variables can show deterministic chaos, a complex behavior indeed. For the natural scientist and the engineer, nearly all their systems are complex [emphasis added]. Many problems still resist the arguments of symmetry, averaging, time-scale separation, and covariation that often underlie complexity reductions.” Experimentally, from a combinatorial perspective of finding the “right catalyst” (e.g., Gobin 2008; Polshettiwar 2009) there is great flexibility for catalyst design but a major challenge in predicting the performance consequences of the catalysts that are created. The systems approach to composite materials and device assembly and design is an intriguing potential route for the control of bio and catalytic processes. Whether or not it will be a commercially successful approach remains to be determined, but there is little doubt but that it will provide a new perspective of complex system design and function. In the first part of the presentation, an example will be given of the use of highsurface-area inorganic interfaces to control the catalytically driven bioprocesses of a biosystem of some complexity. The latter part of the presentation is a selected overview of some recent strategies for the synthesis of multicompositional functional units and their use in controlling processes in chemo catalysis. 2 Inorganic interface control of bioprocesses
This issue is of increasing interest because of the use of silica mesoporous agents as cardiovascular drug delivery agents for the treatment of cancer (Klichko 2009; Park 2009; Slowing 2006) and as gene transfection agents (Radu 2004). In the example presented here, the high-surface-area inorganic phase, which can include a zeolite, mesoporous structure or layered clay structure, is considered as a system in its own right, and is most effective as a porous heterostructure that is capable of acting as a delivery or uptake agent for heat, electrolytes, or large enzymatic biomolecules. The biosystem response is considered in the context of the new total system that is created by its interface with the original unperturbed biosystem. The inorganic interface is also used to probe the network nodes of the total biosystem by monitoring the bioprocess activity response to the interface upon selective depletion of the normal biosystem proteins. The biosystem of interest is the blood clotting cascade, which consists of 122 proteins, including enzymes, that form a system network with 278 known interactions that can be further complicated by anticoagulation agents such as Warfarin and heparin. The system is autocatalytic with the formation of thrombin, which then further catalyzes the activation of the clotting part of the cascade. It is also self-regulating with uncontrolled anti-coagulation catalysis resulting in coagulopathy and bleeding diathesis. Our in vitro studies (Ostomel 2006abc, 2007; Baker 2007, 2008) and in vivo studies carried out by UHUHS (Ahuja 2006; McCarron 2008) have shown that arterial hemorrhaging can be very effectively controlled to give close to 100% survivability (Kheirabadi 2009) by interfacing an appropriate inorganic material with the blood coagulation system and catalytically accelerating the blood coagulation process. The highest efficacy, at low therapeutic material dosage levels, is obtained when a pure silica mesoporous material is used with pore sizes above 24 nm. If the mesoporous material is also used as a delivery agent for thrombin, which can be readily loaded into its 3D cage structure, an even greater efficiency for blood clotting is obtained. The inorganic system variables evaluated in this research with different inorganic agents were composition, heterostructure, time to initiate coagulation, rate of coagulation, strength of the resulting fibrin network, heat transfer, local dehydration of the blood, electrolyte delivery or uptake, zeta potential in simulated body fluid, dissolution or exfoliation of the inorganic phase, accessible protein surface area, and biocompatibility. Studies of the blood clotting cascade system with and without the inorganic are still in progress, but inorganic variables that are highly correlated with the coagulation res-ponse of the biosystem, and most importantly from a mechanistic point of view, specific blood clotting factors, have been identified. The use of the inorganic interface to probe and better map out the processes of this biosystem is expected to continue for some time in the future, and will include microfluidic real time studies and system modeling. The in vivo validation of the in vitro studies carried out in our laboratories ultimately resulted in its adoption for military and civilian use (products commerically available from Z-Medica Inc.). From a pragmatic perspective, approaching this problem as a system problem was very effective. However, one important point must be made in this connection. The tie lines that connected benchtop research, scale-up (including in vitro to in vivo evaluation), formulating a commercial product, and even receiving critical evaluations from medical personnel regarding the pros and cons in field application were exceptional in terms of the short response time and openness of communication. This greatly expedited and facilitated the practical design of the most effective materials for this application. The most important characteristic of any complex system is the function for which it was intended to deliver. This determines the synthesis strategies that are used, the characterization techniques that are applied, and the on-going guidance of the direction of the research. The most serious limitation in systems analysis is the generation of sufficient experimental data to develop a meaningful understanding of the network interactions so that a predictive model can be generated. 3 Interfaces and the multicompositional, hierarchical assembly of functional units
A desirable way to introduce coupled multiple subsystem functionalities is by the integrated, but spatially distinct, organization of domains with different composition. The size, composition and morphology of these heterostructure domains are dependent on the application. If 3D interconnected porous domains are introduced to control residence times in catalytic processes, pore or cage diameters on the order of 100 nm may be in order. For phonon Rayleigh scattering, smaller domain sizes may be appropriate. For oxidation-reduction, electron transport processes such as photo-catalysis (Yates 2009) and photovoltaic applications, two key challenges are electron-hole recombination and the existence of electron trap states at the domain interfaces as well as in the bulk. For photovoltaics, we have shown that the use of semimetal nanoscale heterostructures epitaxially implanted at the charge transfer interface of p-n semi-conductor junctions...
